Passage One

Mount Vesuvius,a volcano located between the ancient Italian cities of Pompeii and Herculaneum,has received much attention because of its frequent and destructive eruptions.The most famous of these eruptions occurred in A.D.79.

The volcano had been inactive for centuries.There was little warning of the coming eruption,although one account unearthed by archaeologists says that a hard rain and a strong wind had disturbed the celestial calm during the preceding night.Early the next morning,the volcano poured a huge river of molten rock down upon Herculaneum,completely burying the city and filling in the harbor with coagulated lava.

Meanwhile,on the other side of the mountain,cinders,stone and ash rained down on Pompeii.Sparks from the burning ash ignited the combustible rooftops rge portions of the city were destroyed in the conflagration.Fire,however, was not the only cause of destruction.Poisonous sulphuric gases saturated the air.

These heavy gases were not buoyant in the atmosphere and therefore sank toward the earth and suffocated people.

Over the years,excavations of Pompeii and Herculaneum have revealed a great deal about the behavior of the volcano.By analyzing data,much as a zoologist dissects a specimen animal,scientists have concluded that the eruption changed large portions of the area’s geography.For instance,it turned the Sarno River from its course and raised the level of the beach along the Bay of Naples.Meteorologists studying these events have also concluded that Vesuvius caused a huge tidal wave that affected the world’s climate.

In addition to making these investigations,archaeologists have been able to study the skeletons of victims by using distilled water to wash away the volcanic ash. By strengthening the brittle bones with acrylic paint,scientists have been able to examine the skeletons and draw conclusions about the diet and habits of the residents.Finally,the excavations at both Pompeii and Herculaneum have yielded many examples of classical art,such as jewelry made of bronze,which is an alloy of copper and tin.

The eruption of Mount Vesuvius and its tragic consequences have provided us with a wealth of data about the effects that volcanoes can have on the surrounding area.Today volcanologists can locate and predict eruptions,saving lives and preventing the destruction of cities and cultures.

1.Herculaneum and its harbor were buried under_____lava.
